HANDLE BAIL AND HANDLE SPRING MEANS FOR CARPET SWEEPERS Filed Jan. 15. 19 32 Z INVENTOR ATTORNEY 5 Patented Dec. 5, 1933 HANDLE BAIL AND HANDLE SPRING MEANS 1 FOR CARPET SWEEPERS Fred W. Pullen, Grand Rapids, 'Mich., assignor to Bissell Carpet Sweeper 00., Grand Rapids,

Mich.

Application January 15, 1932. Serial No. 586,716 I 2 Claims. (01. 15-41) The objects of this invention are:

First, to provide a very simple and compact construction in which the springs are retained under tension and consequently effectively supported in place.

Second, to provide an improved construction of nib and spring connection.

Third, to provide improved means of effectively retaining the pivot connection while at the same time permitting the necessary movement for the proper manipulation of the handle.

Further objects and objects pertaining to economies of construction will definitely appear from the description to follow. v

A preferred embodiment of my invention is illustrated in the accompanying drawing, in

which: v

Fig. 1 is an end elevation view of a carpet sweeper case with my improved bail and spring structure in place, the brush and end bar and driving means being removed so that the detailed construction will fully appear.

Fig. 2 is an enlarged detail vertical sectional elevation, the parts being shown in broken section on line 2-2 of Figs. 1, 3 and 4.

Fig. 3 is an enlarged detail sectional elevation taken on line 3-3 of Fig. 2 showing details of the pivot and retaining means.

Fig. 4 is an inverted sectional plan view taken on line 4-4 of Figs. 1 and 2, showing details of centering arrangement for the said bail.

Fig. 5 is a similar central sectional view showing the action of the bail when the handle is tipped.

Fig. 6 is a detail end elevation view showing a slightly modified construction with the centering stops above the pivots in place of below. r

Fig. 7 is a slight modification of the spring connection.

The parts will be identified by their numerals of reference which are the same in all the views.

1 is the end of the carpet sweeper case. 2 is the bail. 3 are the pivot nibs with necks 31, pivoting in apertures 4 in the end of the case. To one bail member 21 is secured the cross spring clip 5. 6, 6 are the handle springs, bowed upwardly and outwardly and extended downwardly. The end 61 of each spring is driven into the wood of the end of the case and is inclined downwardly at an angle of about eighty degrees. This serves to balance the sweeper handle and avoids the tipping action that occurs when it is not present.

Each pivot nib 3 is retained by plate 7 through which it is inserted and the annular neck 31 is engaged by the side of the aperture 73 in the plate 7, as seen in Figs. 2 and 3. The plate '7 is retained by screws 71, see Fig. 2, and has rounded stops when it is at rest. It can be swung down to either @bail thus provides in effect a yielding stop which 3 assists in holding. the handle in central position side when the carpet sweeper is in use and does not interfere with the free pivoting.

In Fig. 6, I show the projections at 7 4 above the pivot center. While they serve the same purpose, it is not necessary, of course, to providean ex: tension on the bail in this structure.

In Fig. '7 I show the spring 6 as it appears when connected 'to a case with asheet metal end 101,

simply perforated at 102.

I desire to claim the particular details of the construction and also to claim the invention broadly as pointed out'in the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patentis: I. 1. In a carpet sweeper structure, the combination of a case, a bail therefor, a pivot nib at right angles to the said bail end and pivoting in an aperture in the said case, the said nib being formed with a reduced neck, and a retainer plate fastened to the face of the, case and having an aperture for the insertion of the said pivot nib, the aperture in the plate being offset from the aperturein the caseto engage the said neck and retain the 'pivot nib in thesaid case.

2. In a carpet sweeperstructure, the combination of a case, a bail therefor, a pivot'nib at right angles to the said bail end and pivoting in an aperture in the said case, a'spring clip having laterally projecting ears carriedby said bail end,
